mahave shown said features as apphed to woven construction embodying certain of the features shown and described in Letters Patent of the United States No. 1,025,419, issued May 7, 1912, to Robert S. Moss. However, it Will be understood that in so illustrating the present features of invention we do not in any wise limit ourselves to their application in this particular manner.

In the several drawings, the coke oven proper and the combustion fines for heating the same are shown as built into a super-structure, 7 while the passages or lines for the eduction of the burnt gases and for the preheating of the incoming air are shown as contained mainly in a sub-structure? 8. The retort for the coal for other carbonizing material is designated 9. A plurality of combustion flues 10 are arranged in U-shaped fashion around the sides and bottom .ofthe coking retort. Into the upper portion of each of these combustion flues there depends combustion lines which it is intended to control. In accordance with the principles disclosed in the above mentioned Letters Patent, the particular arrangement herein represented is one in which the induction ends of the combustion. flucs alternate on the two sides of the retort, so that the flow of burning gases in each combustion flue is in the direction opposite to that, in the adjacent. lines. This arrangement will be readily understood from airiuspcction of Figs. 1 and which are sections taken through adjacent portions of the structure. ()ne of the upper ends 15 of each cmnbustioii flue communicates with a downwardly extending flue l6. the. lower end 17 of which bends over and comn'iunicates with a longitudinally extending discharge Hue 18 which leads to the stuck or other draft producing means as best. shown in Fig. 3. The arrangement thus far des'ribed is of fai'niliar construction, and we will not further detail the same at this point.

In order to carry the distillate gases immcdiatelyanuiy from the carbonizing mass a pair of passages 19 extend throughout the length of the oven, being conveniently located in the upper or roof portion of the super-structure... A plurality of communicating ports or the like 20 extend from the.

upper portion of the retort into the passages 19, said ports being conveniently spaced, preferably in alternate relation throughout the length of the oven so as to permit the distillation products to rise from the retort into the passages 19 without having' to travel any appreciable distance. lVith this arrangement it will be apparent ,thatfcracking or splitting of the prod ucts will be overcome inasmuch as they will not remain for any appreciable length of tune in contact with the hot walls of the retort.

In order to still further insure that the temperature of the distillation products will not rise above their distillation temperature and in order to better control the coking operation, it is preferred that the temperature of the upper or roof portion 21 of the retort proper shall be maintainethapproximately at the temperature at which the products of distillation are passing off. As a simple means accomplishing this result weprovide a dome above the carbonizing material, which dome is not directly heated by the combustion fines. andv into which dome the distillation products immediately rise. In the particular arrangement illustrated this dome constitutes the upper portion of the retort, and the upper ends of the combustion flues do not extend into the walls of the dome but terminate below it so that itis not directly heated. lVhile we have herein shown the .dome as being the upper portion of the retort, and '.as being the p'o i'tion which is not directly heated by the COlllblIStlOIl fines. such construction being shown by way of illustration, still it will be seen that there are peculiar-relationships between a dome placed in the upper portion of the retort and the particular arrangement of heating flues illustrated. For

example. the gases of combustion in the heating or combustion fines are being drawn down away from the dome, so that the fact that they do not directly heat the dome is all the more pronounced.

It will be. seen from a study of the arruugementthus far particularly cmisidered.

.that the dome and the passages are so related and incloscd that the products of distillation passing olf through them are. not cooled. but are allowcdto pass-off at the same temperature as that at which they are dis tilliug. It. therefore, follows that the arrangement is such that the products of distillation'are neithia' cooled to causethem to precipitate their tarry constituents, nor heated above. their temperature ofdistillation to cause them to break down or'crack into lighteror poorer constituent gases.

Each of the air lines 13 has its lower end.

in communication with a longitudinally extending passageway 2E By reason of the alternating relationship of the U-shaped combustion fines, each of the air lines 13 provided with a .plurality of vertical pas-vsages, alternate ones of the passages in each heating wall being spent gas" passages, and the intermediate passages of said heating wall being air passages of a sub-structure on which said coke oven is mounted, said substructure havinga longitudinally extending spent gas tunnel, a pair of air tunnels lying adjacent to said spent gas tunnel, other air tunnels lying adjacent to said first men tioned air tunnels and in communication therewith, connections from the lower ends of the spent gas passages to the spent gas tunnel, and connections'from the lower ends of the air passages to'the adjacent ones of the second mentioned air tunnels.

The combination with a coke oven having heating walls, one of said heating walls being provided with a plurality of vertical passages, selected ones of said passages being spent gas passages, and other of said passages being air passages, of a sub-structure on which said oven is mounted, said substructure being provided with. a spent gas tunneh'and with a U-shaped air tunnel, one

arm of said U-shaped air tunnel lying adjacent to the spent gas tunnel, connections- Lassen) from the lower ends of the air passages to the other arm of said U-shaped air tunnel, and connections from the lower ends of the spent gas passages to the spent gas tunnel.
